COOPERATIVE COMMUNICATION SYSTEM, TRANSMITTER, RELAY AND RECEIVER, USING NETWORK COMPRESS-AND-FORWARD SCHEME

摘要

PROBLEM TO BE SOLVED: To provide a network framework practically using theoretical coding method for a network compress-and-forward scheme.SOLUTION: A cooperative communication system includes: a transmitter 110 that generates a codeword from a plurality of data blocks on the basis of a long message encoding scheme, and multicasts a signal including the codeword; a plurality of relays 120 configured to receive the multicasted signal, encode the multicasted signal independently of other relays to generate a random-mapped signal of the plurality of data blocks, and relay the random-mapped signal; and a receiver 130 that receives a plurality of signals relayed by the plurality of relays, and generates the plurality of data blocks from the plurality of signals on the basis of a joint decoding scheme.
